Just to add to your point, typical operating range for white LEDs is about 10-20mA, and most lights I've seen take at least 3.

3600mAh (whether Li-ion or three typical AAA batteries) only gets you about 60-120 hours powering 3 white LEDs. Over a year, that's like 10-20 minutes of light a day.

This is why it might work in a closet, set to motion activated, where you only need it for a few minutes at a time. But not gonna cut it for extended use.
